A fish is any of a large group of cold-blooded, finned, aquatic vertebrates that respire by passing oxygenated water over gills. NO fish can breathe through lungs and ALL fish have wet scaly skin
Tigers are vertebrates, all mammals are vertebrates because they have an internal skeleton that includes a spinal column. Tigers also have the other characteristics of vertebrates: a head, central nervous system/brain, and a neural tube. See related questions and links for additional information about vertebrates.Vertebrate
Reptiles are cold-blooded vertebrates that have scales or scutes covering their bodies. They lay eggs on land and breathe air through lungs. Reptiles are ectothermic, meaning they rely on external sources of heat to regulate their body temperature.
Genitals
Yes. All vertebrates are in the Phylum Chordata.
they all have a back bone
There are actually five characteristics that all vertebrates have in common; a vertebral column composed of multiple vertebrea (spine), a cranium (the bone that envelopes the brain), a closed circulatory system, nural crest, and a pronounced cephalization.
which characteristic do all vertebrates have in common as embryos
Squirrels are vertebrates, they have spines.
They all have long, worm-like snake bodies. Their teeth are also retractable and they are all carnivores.
Yes, Pythons are vertebrates as they have a backbone.
Vertebrates is the name of a taxon, a clade in biology. The most important defining characteristic of this group is that they all have vertebrae.Within this group are many subgroups, which have slightly different characteristics, but all share the defining characteristics of the larger group (the vertebrates).The group vertebrates itself is a subgroup of a larger group. Together with a couple of other groups, it is part of the group Chordata. The most important defining characteristic of this group is that the animals in it all have a central nerve chord along the length of their bodies. Vertebrates and all its sister-groups share this trait, and all the other traits of the larger group, but differ in others (eg. not all chordates have vertebrates).It is this pattern of nested hierarchies, sets within sets within sets, each set sharing the defining characteristics of the superset, but differing in others, that made naturalists conclude that the diversity of life is the product of a process of continuous divergence: evolution. In this model, a superset (ancestral form) produces lineages (subsets) with diverging characteristics. Each of the diverging lineages keeps many of the characteristics of the ancestor, but becomes increasingly different from the ancestral form and its sibling lineages in other aspects. It is this pattern that tells us that all vertebrates have a common ancestor that was part of the clade of Chordata.
The strong evidence for the common ancestry of all vertebrates is THE SIMILARITY OF THEIR EMBRYOLOGICAL STAGES.
No, all tigers are vertebrates, as are all mammals. They have a vertebral column, a backbone, and an internal skeleton which are main characteristics of vertebrates.
Yes, skunks, like all mammals are vertebrates because they have backbones, one of the main characteristics of vertebrates
Yes. Anacondas, like all reptiles, are vertebrates. They have a backbone and an internal skeleton, which are the characteristics shared by vertebrates.
Yes. As all vertebrates, they have an internal skeleton to give their bodies stability.
